Cther objects or the invention are to provide apparatus of thecharacter described comprising a plurality ofpivotally mounted tool-carrying elements; to provide a drill and a mortiser associated with each of said elements; to provide in connection with one of said elements a mortiser for cutting alock mortise; to provide in connection with the other of said elements a mortiser for cutting a-l'ock face mortise; to provide in connection with each said pivotally mounted element for insuring the proper position ertne cutting tools associated therewith; to; provide means in connection with the workweeeiving table to propeny position thereon any door of standard pl'fe'dete'ifihined thickness p v I Other objects of the invention will in part be obvious and will in part appearhereinafter. v

The invention accordingly comprises theapparatuseihbodying' features of (iol'istriiction, combination of ements and agren gemen or parts-e11 as exemplified in t11efo1lowing detailed disclqsure, and the seope er th application of which will be indicated in the claims; 7

For a fuller understanding" of the invention, reference should be had to the following detailed on, taken in cofinebtifih with the accomgs, m which: I Figure-1 is a plan new or apparatus embodying one form 'of the 'iiiveiitin and Fig. 2 is an enlarged verticei section or the apparatus shown if) Fi 1- taken along the line 2-4' therein.-

There is increased dehlafid today for large numbers or re ly'i re houses. This emand has one u in part-tram the eirort o! in.

dus'try to provide adequatev housing for its employees', and. more recently from the. increasing demands for adequate housing in connection with the rapid development of war industries. Prefabricated dwellings have been. suggested as one answer to this housing problem. In dwellings of this type and inthe cheaper type of individual dwelling construction it is customary to employ doors of standard sizes, and more specifically doors of standard thickness. This is true even where the height and width of the door employed may vary slightly with. its use in the dwelling. Practically every door is provided with. a lock, and the cutting. of the necessary holes to accommodate the lock, thelock face plate and the spindle for th door knob has been an element of considerable cost, especially where a great number of dwellings are being. erected and many thousands of doors used. This invention has for its object essentially the provision of apparatus which will facilitate the cutting of the lock mortises,.1ock holes, sp'indleholes, and lock face mortises, especially where large numbers of doors of the same thickness are to be out.

In the embodiment of the invention shown in the drawings, H3 represents a worli-re::eivin.5:v table. Along one edge of the table there is provided an abutment element l2 which may be, for example, an angle iron bolted or otherwise .afiixe'd: to the top 14 of the table. The table top my be formed of any suitable flat element, preferably aplywood panel, as shown for example most clearly in Fig. 2. The work, i. e., the door which is to be cut, and which is shown as at I6 in Fig. 2 in dotted lines, is preferably supported above the table top M on spaced elements It to facilitate movement of the work upon the table.

The front or work-engaging edge of the table top is provided with a plurality of spaced abutmerit elements 20 which are positioned perpendicular to the abutment element I2, and which in connection therewith determine the position of the work upon the table. The upper portion 14 of the table is cut away, as shown most clearly in Fig. 1,. in the center of'the table and along the front edge thereof, as at 22, to provide a recess for the reception of the drills and mortisers employed in connection with the use of the apparatuses hereinafter explained. As is apparent also from Fig. 1, this portion. of the table is free fromv the abutment elements 20. The cut-away portion or the: table top l4 providing the recess 22 extends substantially back of theedge' ofv the workwhichis to be moms-ea aiid armed and. which is: in close contact With-the abutment elements 20. There may be provided at the opposite end of the table to that equipped with the fixed abutment element l2 an adjustable further abutment element 24 which may be moved into contact with the edge of the work thereadjacent and fixed in position so as to assist in holding the work in proper position upon the table. This abutment element, however, is not essential to the operation of the device. The elements 12 and 20 function adequately to insure proper positioning of the work upon the table.

Positioned beneath the table top l4 and ex tending beneath the recess 22 therein is a supplemental platform or table 26 adequately supported on the frame of table ill by the arms 28; Platform 26 carries thereon two tool-supporting elements 33, 32. Element 30, the right-hand element shown in Fig. l and that element shown in Fig. 2, is pivoted, for example at 34, and is provided with one or more roller supports 36 traveling upon a rail 38 carried by element 33. Element 32 is similarly pivoted at 40 and is similarly provided with one or more rollers 42 riding upon rail 44 on the surface of platform 26. Elements 30 and 32 may be movable from, for example, the position shown in the drawings to a position in which the cutting tools carried thereby are in operative engagement with the door or other work It. Each tool-carrying'element 3B, 32 is provided with a plurality of clamps 43 which are adapted to engage the door or other work to be out and thus secure proper, firm positioning of the cutting tools with respect to the work.

It will be understood that the drawings show only diagrammatically the cutting devices which are to be employed in the practice of the invention. These devices .are standard. Each toolsupporting element 30, 32 is provided with a drill 53 suitably mounted thereon, one drill, for example that carried by element 30, being adapted to drill the lock hole in the door, and the other drill, for example. that carried by the element 32, being adapted to drill the spindle hole in the door. These drills are preferably power-driven, manually controlled, and equipped with suitable stops and controls for insuring proper cutting of the work. It is immaterial in the practice of the present invention whether the drill associated with the element 30 is adapted to cut the lock or the spindle hole, and the details of tool construction are not part of the present invention. It will be apparent to anyone skilled in the art what tool should be employed for the specified purpose and where it should be mounted on either carrier Each carrier 30, 32 is equipped also with a power-driven lock mortiser 52. Here again the tool construction is not part of the present invention, and either mortiser, for example that carried by element 30, may be adapted to cut the lock mortise, and the other mortiser, for example that carried by element 32, may be adapted to cut the lock face mortise in the door. Again the selection of tool and proper positioning on the tool carrier will be obvious to those skilled in the art,

cutwith arouter, it has been found that inthe practice of the present invention duplicate machines may be employed to cut the lock mortise and the lock face mortise.

In the practice of the present invention a door to be cut is placed upon the elements I8 and moved into position against the abutment elements l2 and 20 with the portion of the door to receive the lock positioned over th recess 22 in the table top l4. Normally the bottom of the door will rest against abutment l2. One or the other of the pivotally mounted tool-carrying carriages 30, 32 is then moved from the position shown in the drawings to a position in which the clamps 46 are adapted to engage the work [6. To insure proper positioning of the carriages a stop 54 may be provided at the ends of the rails 38, 44 and when the foremost roller 36, 42 of each carriage makes contact with the stop, the carriage will be in proper position with respect to the work. The clamps 46 are then affixed to the work and the operator then cuts either the lock mortise or the lock face mortise, as the case may be, and drills eitherthe lock hole or the spindle hole, as the case may be. When the work is completed the clamps are released, the carriage is swung back in the position shown in the drawings, the other carriage is moved forward into work-engaging position, and the remaining mortise is cut and the remaining hole drilled.

With apparatus of the type described a vast number of doors can be prepared for the reception of the lock rapidly and at little expense. Whil the saving in cost per door may not be great, the over-all saving in the manufacture of thousands of doors is substantial.

Certain modifications of the invention will be apparent to those skilled in the art.. For example, the tool-carrying elements may be mounted in other ways to be moved into and out of engagement with the work. So also, other forms of work-receiving table may be employed. The work may be clamped directly to the table, for example,

.and the tool-carrying elements may be locked into operative position by any suitable means which prevents their movement with respect to the table itself. Under these circumstances the clamps carried by the elements 30, 32 maybe dispensed with. Other similar modifications in the apparatus will be obvious to those skilled in the art.
